Approach to Developing Interleaved Converter with Single-Capacitor Turn-Off Snubber

Abstract:

This paper presents a systematic approach to developing turn-off snubber for an interleaving converter to smooth out switch turn-off transition. With the approach, the interleaving converter with two turn-off snubbers, which are formed by two L-C-D type snubbers, can be replaced by the one with turn-off snubber composed of a single-capacitor snubber. It can be used in the basic six interleaved converters, such as buck, boost, buck-boost, ‘cuk, zeta and sepic converters. In this research, the structure of the interleaved converter with the turn-off snubber can be conveniently simplified from the derived general configurations, reducing the complexity of circuit structure significantly. Measured results from a buck prototype converter have been verified to prove the feasibility of the derived turn-off snubber.
